[0026] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0027] Please see Figures 1-4A special overlocking device for perforated fabric includes a sewing mechanism 1, which includes a base plate 101. An overlocking machine body 102 is fixedly connected to the top of the base plate 101, providing support for the overlocking machine body 102. A folding mechanism 2 includes a guide plate 201 fixedly connected to one side of the top of the base plate 101. Studs 202 are symmetrically fixedly connected to one side of the top of the guide plate 201. Nuts 204 are threaded onto the outer sides of both sets of studs 202. C-shaped plates 203 are rotatably connected to the outer sides of both sets of nuts 204. The nuts 204 are used to drive the C-shaped plates 203 up and down during rotation, thereby adjusting the distance between the C-shaped plates 203 and the guide plate 201 to press and guide perforated fabrics of different thicknesses. The C-shaped plate 203 is set on the top of the base plate 101. The C-shaped plate 203 is used to guide the hollowed-out fabric to be hemmed, so that the hollowed-out fabric can be folded after passing through the inside of the C-shaped plate 203.
[0028] A tongue plate 207 is fixedly connected to one side of the bottom of the C-shaped plate 203. The tongue plate 207 is used to guide the fabric into the interior of the C-shaped plate 203. Multiple L-shaped guide strips 206 are evenly fixedly connected to one side of the guide plate 201. Each set of L-shaped guide strips 206 passes through one side of the C-shaped plate 203, guiding the up-and-down movement of the C-shaped plate 203. A reinforcing plate 205 is fixedly connected to one side of the top of the C-shaped plate 203. Each set of L-shaped guide strips 206 slides through the reinforcing plate 205. Two sets of nuts 204 are rotatably connected to the reinforcing plate 205. Multiple reinforcing ribs 213 are evenly fixedly connected to the top of the C-shaped plate 203. Each set of reinforcing ribs 213 is fixedly connected to the reinforcing plate 205. The reinforcing plate 205 and reinforcing ribs 213 improve the strength of the C-shaped plate 203, thereby reducing the probability of deformation.
[0029] A matching baffle 208 is slidably connected inside the C-shaped plate 203. The baffle 208 is used to limit the fabric extending into the C-shaped plate 203. Multiple sliders 211 are evenly fixedly connected to the top and bottom of the baffle 208. Sliding holes 210, matching the sliders 211, are provided on the upper and lower sides of the C-shaped plate 203. Each set of sliders 211 is slidably connected to the C-shaped plate 203. The sliding holes 210 and sliders 211 guide the sliding of the baffle 208. Anti-fall blocks 212 are fixedly connected to the top of each set of upper sliders 211. Each set of anti-fall blocks 212 is located on the top of the C-shaped plate 203 and serves to limit the movement of the sliders 211.
[0030] An adjusting screw 209 is rotatably connected to the side of the baffle 208 away from the stud 202. The adjusting screw 209 is threadedly connected to the C-shaped plate 203. The adjusting screw 209 is designed to move the baffle 208 when rotated, thereby adjusting the width of the fabric that can be inserted into the C-shaped plate 203, and thus adjusting the width of the overlock. Multiple sliding rods 214 slide through the top side of the C-shaped plate 203. A U-shaped frame 215 is fixedly connected to the bottom of each set of sliding rods 214. A pressure roller 216 is rotatably connected inside each set of U-shaped frames 215. The pressure roller 216 is designed to press down the fabric after folding, so as to reduce the probability of the fold coming undone again. Each set of sliding rods 214 is fixedly connected to a traction plate 217 at its top. Each set of traction plates 217 is fixedly connected to a spring 218 between it and the C-shaped plate 203. The spring 218 is designed to use its own elasticity to pull the traction plate 217, sliding rods 214 and pressure rollers 216 downward, thereby pressing the folded edge of the fabric.
[0031] In this embodiment, the overlock machine body 102 is existing technology and will not be described in detail here.
[0032] In use, the edge of the perforated fabric to be locked is passed between the two sets of guide plates 201 and the C-shaped plate 203, and then introduced into the interior of the C-shaped plate 203, thereby folding the edge of the perforated fabric to be locked. Then, the adjusting screw 209 is rotated according to the required width of the locked edge, so that the adjusting screw 209 drives the baffle 208 to slide inside the C-shaped plate 203 when rotating, thereby adjusting the width of the perforated fabric that can be inserted into the C-shaped plate 203, until the width of the perforated fabric inserted into the C-shaped plate 203 is adjusted to match the required width of the locked edge. Then, the two sets of nuts 204 are rotated, so that the nuts 204 drive the C-shaped plate 203 downward when rotating, until the distance between the bottom of the C-shaped plate 203 and the guide plate 201 is adjusted to match the thickness of the perforated fabric. Next, the sliding rod 214 is pulled upward, causing the sliding rod 214 to drive the U-shaped frame 215 and the pressure roller 216 to move upward. Then, the folded fabric pulls the sewing part of the base plate 101 and passes under the pressure roller 216. Then, the sliding rod 214 is released, causing the spring 218 to pull the traction plate 217 and the pressure roller 216 downward, so that the pressure roller 216 presses down on the fabric. Then, the base plate 101 can be activated to pull the fabric and sew the folded edge, thereby achieving the hemming of the fabric. During the process of hemming the fabric, the side of the fabric that passes through the inside of the C-shaped plate 203 can be guided and flipped, so that the worker does not need to fold the fabric frequently, thus effectively improving the efficiency of hemming the openwork fabric.

They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
